If I confronted her now, in this kitchen, with nothing but my own word against hers, she would deny it, dispose of the jar, warn her accomplice, and vanish the evidence — and I would be left a hysterical wife accusing a beloved grandmother of an impossible crime, with nothing to show for it but a rinsed cup.

The only power I had was her ignorance of what I knew.

So I held still.

I watched a woman prepare to kill me and I did not move, because moving would have warned her, and I needed her to keep believing she was safe for exactly as long as it took me to build something that would hold in a courtroom.

It was the hardest stillness of my life.

I have thought since that it is the same stillness my daughter had found days earlier, when she saw the same thing and chose not to cry out but to lean close and whisper.
